Fold 1/2 cup black beans, 1 tablespoon salsa, and 1 slice cheddar cheese in a small flour tortilla. Cook in a dry nonstick pan until the cheese is melted and tortilla is lightly browned. Then wrap it in foil and stick in a plastic baggie for easy transport.
The colon (large intestine) is a distal part of the gastrointestinal tract, extending from the cecum to the anal canal. It receives digested food from the small intestine, from which it absorbs water and ions to form faeces. Anatomically, the colon can be divided into four parts â ascending, transverse, descending and sigmoid. These sections form an arch, which encircles the small intestine.
Sigmoid colon, a terminal section of the large intestine that connects the descending colon to the rectum; its function is to store fecal wastes until they are ready to leave the body. The sigmoid colon derives its name from the fact that it is curved in the form of an S (Greek sigma: Ï). Its size depends upon the amount of waste material in it, but when contracted its diameter is only about one inch (2.5 centimetres).
